aptitude install mariadb-server mariadb-common php5-mysql

Ensuite on peut lancer un script pour améliorer un peu la sécurité :

 mysql_secure_installation

 mysql -u [user] -p

 CREATE USER '[nom]'@'localhost' IDENTIFIED BY '[password]';

 CREATE DATABASE [db name];

 GRANT [PERMISSION] ON [db name].[table names ou *] TO 'user'@'localhost';
 FLUSH PRIVILEGES;

 SELECT User FROM mysql.user;
